Delta Motor Speed Controller
To change the controller parameters, use the buttons on the keypad to select the
desired settings (see “Speed controller parameter settings” table below):
a. PROG/DATA: press the “PROG DATA” button to initiate program mode;
then the following screen will appear:
This screen indicates which parameter number is selected (see table below),
which in this case is parameter 0. Press the up or down arrow button to
select the desired parameter number (0; 1; 2; 6; or 7). Press the
PROG/DATA button again to reveal the second set of numbers (on the right
side of the dash in the “parameter” column of the table below). Use the
arrow buttons to select the desired number. After completing the desired
combination of numbers, press the MODE button twice to return to the home
screen.
b. MODE: press the MODE button to display information about the status of the
drive. Successively pressing the MODE button displays different information.
For example, pressing the MODE button 3 times displays the current speed
(in rpm’s) of the turntable. (E.g. 12rpm displays as “u 12”.)
c. Arrow keys: press the up or down buttons to scroll through different
parameters. Press the up or down arrow key quickly to change parameter
settings in single unit increments.
d. The following table indicates the controller settings for each model that are
required to achieve a minimum rotation speed of 3rpm and an upper rotation
speed of 12rpm:
